Statement: If a polygon is a parallelogram, then it is not a trapezoid. What is the contrapositive of the following statement?
A If a polygon is a parallelogram, then it is a trapezoid.
B If a polygon is a trapezoid, then it is not a parallelogram.
C If a polygon is not a parallelogram, then it is a trapezoid.
D If a polygon is not a trapezoid, then it is a parallelogram.

I think it is C but I'm not completely sure about the answer

Step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1

good job you smart son of a gun you are smarter that einstein. 7
